| |
Hi,
I have been looking at the CONFIG_HOTPLUG_CPU option in the Linux Kernel. The option works for IA64, PPP64, S390 architectures. I am doing my research on SMT architecture and want to write a kernel module that can dynamically enable/disable SMT, so that I can switch between uniprocessor mode and SMT mode. So is it possible to use the CONFIG_HOTPLUG_CPU option to dynamically enable/disable a logical processor by performing a logical removal of the CPU since the hardware does not support CPU hotplugging? Also I would like to know how efficient such an implementation would be?
I would really appreciate if anyone could provide me suggestions and any specific patches related to this work.
Regards, Jayush.
